The next step toward a finite-size correction for S N (q) and V N /N is given by the analysis of different local field corrections presented in Fig. 13 for the same conditions.
WebSep 30, 1997 · Free energies of ionic solvation calculated from computer simulations exhibit a strong system size dependence. We perform a finite-size analysis based on a dielectric-continuum model with periodic boundary conditions. That analysis results in an estimate of the Born ion size. Remarkably, the finite-size correction applies to systems with only … WebDec 29, 2014 · With free boundary conditions, the finite-size “shift” is greater than the rounding. Nonetheless, using T − T L , where T L is the finite-size pseudocritical temperature, rather than T − T c , as the scaling variable, the data do collapse onto a scaling form that includes the behavior both at T L , where the susceptibility χ diverges ...
